This application is adivision of application Serial No. 736,009 ofCharles Froesch filed Septemberb, 1924.

The present invention relates'to Window constructions, adaptedparticularly for use in vehicles and moving bodies, where the motionth'ereof'causes a vibration and irregue lar movement of the windowframe. jectof the invention is to provide a window structure of theabove type which affords an easy adjustment of the position of thewindow and a 'securing'means which positively, yet yieldingly, securesthe window inv a desired position. I

A'further objectis to provide astructure which will permit-the window tobe raised to a fully opened positionwhere it is necessary to out downthe head room so that the move-' ment of the window to such positionisnot in the plane'ofthe side of-the body.

A still further object is to provide cushioning elements which enablethe window to be secured in position without noise or rattle. These andother'objects will appear in the following description of the inventiontaken in connection with the accompanying draw ings wherein':

Figure 1 is a section taken in atransverse plane of a vehicle bodyshowingin detail a window casement and sashaccording to the presentinvention.

FigureQ is a fragmentary view showing a portion of the window casementand structure whereby it is assembled.

Figure 3 is a section taken on line 3-3 ofFigure 2 and looking in thedirection of the arrows.

In the drawings a represents-the side of a body, for example, a bus bodyhaving an outer shell (4 and an inner shell (1.? running continuouslyfrom the lower edge of the body upon one side of'the vehicle to thecorresponding edge upon the opposite side of' the vehicle; These shellsare secured to.- geth'er by suitable spacing strips or connectingelements in any desired manner.

Conveniently placed in these vertical sides are window. openings (iThese openings are formed by cutting out suitable apertures in theshells a, a and-fittingtherei'n suit-able pressed metal windoweasements. The easements may comprise a suitable window sill portion itformed of pressed metal and preferably welded to the shells a, a?

and inner side frame members h welded on the one hand to the inner sideof the shell a and on the other hand to a pressed metal channel 72, Apressed metal outer reeaosz frame member if is adapted to be securedoutwardly ofthe shell a and to form with the channelh 'a recess for thereception of a block 2' of yielding non-metallic material whichispreferably recessed upon opposite sides to form a bar of materialhaving the cross section of a dumb-bell and adapted to engage throughplate Z with a roller j carried on thewindow sash indicated in generalat m. The roller 'jis adapted to travel in a guide formed'by-apressed'metal angle is, one arm of-which is welded to the chan nel kandthe otherarmof which'is welded to the inner frame member h, while theother side of the guide is formed by an angle Z slidable in a'transversedirection with respectto the outer frame member if and adapt ed to bemaintained yieldingly against the roller by means o-f-the rubber cushioni.

The inner window frame member k. may

be grooved as at k to receive a s'tripof yielding non-metallic materialnengaging the end of the window sash m and yieldinglypressing the windowoutwardly to mainta n the rolleralways against'the guide Z. GuideZ'is'recessedatintervals as at;l for the reception of the roller jwhereby the windowinay be retained at predetermined points partiallyopeirto the desired degree. Guides Z and mare turned inwardly at theupper end of the window opening as at L', K, and serve" to receivethesash when in fully open position, a'strip of yielding non-metallicmaterial 0- being retainedby suitable retaining member 0" at the upperend of the guide portion L to engage'the top edge of the sashand'yieldingly n'iainv tain it in open position, the lower edge of thesash resting then in the recess Pin the guide Z. The topof thewindow'is'closed' by a bent metal frame member pformed with a recess 2for the receptionof arubber'cushr ion eleinent adapted to engage theupper end of the sash to prevent rattling when closed position.Toreceive the end of the sash in,

closed position'for' convenience inassembly the top frame member may beformed in two pieces, an inner top member p being welded to the innershell (0' as-wil'l be clearly apparent from an inspection of Figure '3and so formed as to provide a clearance for the upper end of the sash inopening and closing the window. As a re-ent'orcing element and to serveas an enclosure for the sash in fully open position a plate 9 of pressedmetal may be secured to the top portion of the inner shellja at itsupper end and to the Vertical portion of the inner shell member at itslower end, an opening 9 being formed in the lowermost portion thereoffor the reception of the handle m of the sash.

It will be seen that the construction described herein provides a windowwhich may be moved to any desired position and which is secured againstrattling in such position. The cushion elements are easily installed andthe entire structure maybe assembled with great facility.

Although a specific torinof the invention has been shownherein, it isnot to be inter- ,preted as being limited by such disclosure,

save asdefined in the appended claims.

What I claim is: i

1. In an adjustable window, a casement, a

4 sash, tracks comprising fixed strips and movablestrips carried withthe easement, yieldingnon-metallic material interposed between thecasementand the movable strips, rollers on the sash'and positionedbetween the fixed and movable strips, removable face plates on thecasement, and means to secure the plates in telescoping position withrespect to the movable strip to. confine the yielding material; betweenthe plates and movable strips under compression, whereby movement of thef sash is yieldingly resisted.

2. In an adjustable window, a casement, a sash, tracks comprising fixedstrips and movable strips carried with the easement, a flange on eachmovable strip, yielding non-metallic material engaging the movablestrips, rollers on the sash and positioned between the fixed and movablestrips, face plates on the casement, a flange on each plate and overlapping with the flange on the, movable strips,

and means tosecure the plate in position to confine the yieldingmaterial between the plates and movable strips under compression,

Wherely movement of the sash isyieldingly resiste f3. In an adjustablewindow, a pressed metal casement provided with inturned fianges,fixedguides formed on the easement tracks, yielding non-metallic materialinter posed between the casement and the movable portions of the tracks,said yielding non-metallic material being maintained under a degree ofcompression, whereby movement of the sash is yieldingly resisted, andyielding non-metallic means at the end of the exten sions to engage thetop of the window when the sash is lifted toa wide open position.

5. In anadjustable window, a casement, tracks comprising opposed fixedand movable portions carried with the easement, yielding non-metallicmaterial interposed between the casement and the movable'portions of thetracks, said yielding non-metallic material being maintained under adegree of compression, a sash rollers on the sash and positioned withinthe tracks, and yielding non-metallic means on the easement and engagingthe sash on the side opposite to the movable portions, whereby theroller is normally urged-against the movable portions and away from thefixed portions. 1. i I V 6. In a vehicle Window, a casement between theinner and outer sides of the vehicle body, a recessed portion formed onthe inner side of the top of the vehicle body adjacent the topof theeasement to permit the top of the. window sash to be moved inwardly,said recessed portion comprising a plate secured to the inner sideofthe. body and having side portions, tracks on the casement, and means topermit the top of the sash to be raised in a plane at an angle to thecasement comprising extensions to the tracks on the side portions of theplate.
